yuck mouth

That taste you get in your mouth when you realize that the really cool set of bagpipes you found in your grandma's bathroom closet and wrapped your lips around was in fact her vintage douche bag.

Andrew still has the yuck mouth to this day from playing grandmas bagpipes

bible-mouth 

In CB slanguage, a Sultan of Slang who uses so much slang that even other Sultans of Slang have to look up what they're saying in the CB Slanguage Bible to understand what they're saying.

When a bible-mouthed gunnybagger ratchets his jaw, (see ratchet jaw), he done blow your doors off for sure.

Your mouth is open 

Speaking without authority or unclearly.

Usually used amongst friends, can be a merciful out for a person who starts talking and realizes halfway through their speech that they haven't a clue what the point they were trying to make was.

Your stoned friend who keeps endlessly blabbing on and on about the blue dophins of conciousness holding his eyelids open with a toothpick could be quickly shut up by being told "Dude - your mouth is open!"
